Dear sir
I want to use graphical lcd in my project.but I do not know how to communicate with it.Can 8051 interface with graphical lcd128x64?if not which G.Lcd can interface with 8051.I want to know commands of G.LCD.Please give details.
 

check out the memory requirements( the content you want to display), peripherals required, refreshing rate(speed), if ok its fits in your application.
 

Which variant of 8051 you are using like AT89c51, AT89c52 etc. I already interface 128x64 with AT89c51 without any problem, However, I could able to display few images because of small EEPROM inside
 

Thank you for Reply.I am using AT89c52.

Thank you for Reply.I am using AT89c52 & using keil uvision3
 

Then I am sure you will not face any problem to interface GLCD. Keep in mind there is two enable for 64 + 64 bit page. Each time you can write on one side of GLCD page
 

Dear sir,one more problom now I am facing is in RTC code.The program starts executing & lcd(16x2)shows initial message as mentioned in code but stops in next step & date & time not displayed.
 

Which RTC are you using????
Maybe, after displaying initialized message on LCD then your program hangs on RTC code and stop working. you just debug RTC code or try to comment ur RTC routine and run ur program to make sure that problem will be in only RTC routine.

Hope u understand.
